Test the claim that the mean GPA of night students is larger than 2 at the 0.01 significance level. The null and alternative hypothesis would be: Ho p≥ 0.5 Ho:p ≤ 0.5 Ho: ≤ 2 H₁ p < 0.5 H₁:p> 0.5 H₁:μ> 2 The test is: right-tailed left-tailed two-tailed Based on a sample of 35 people, the sample mean GPA was 2.04 with a standard deviation of 0.08 The test statistic is: The p-value is: Based on this we: Ho:μ ≥ 2 Ho:p = 0.5 Ho:μ = 2 H₁:μ< 2 H₁:p 0.5 H₁:μ ‡ 2 O Fail to reject the null hypothesis Reject the null hypothesis (to 2 decimals) (to 2 decimals)
